How to compress gltf . files

I use Substance Painter and Blender to save glb or gltf files, I see the advantage of compressing files with EXT_meshopt_compression , KHR_texture_basisu , KHR_draco_mesh_compression, so how do I use them to compress my glb file? , can anyone help me? .
Thanks

The issue mentions Substance Painter, Blender, GLB/glTF, and the EXT_meshopt_compression, KHR_texture_basisu, and KHR_draco_mesh_compression extensions, but names no repository file, test, or entry point. Clarify which workflow or documentation is needed, with completion defined as a reproducible compression procedure.
